Pressure plugging is a common construction technology used to prevent liquid or gas leakage or external substances from entering the seal during the construction process. It is widely used in various industrial fields, such as petrochemical, construction, water treatment and so on. In this paper, we will introduce the construction technology with pressure plugging in detail, and discuss its principle, procedure and application.

1. Principle of sealing with pressure

The principle of pressure sealing is to prevent liquid or gas from passing through by applying pressure to the blocked area. This is usually achieved through the use of sealing materials such as rubber, plastic or metal. When pressure is applied, the sealing material is tightly attached to fill the sealing area, thus preventing the leakage of the medium or the entry of external materials.

2. Steps for sealing with pressure

Construction with a pressure plug includes the following steps:

2.1 Preparations: Before performing pressure plugging, some preparations need to be made. This includes cleaning the blocked area to ensure that there are no obstructions or dirt affecting the seal. At the same time, it is also necessary to choose the appropriate sealing materials and tools.

2.2 Selection of sealing materials: Select the appropriate sealing materials according to the actual situation. Under normal circumstances, rubber is one of the commonly used sealing materials because it has good sealing performance and chemical corrosion resistance. However, for special environments and media, it may be necessary to choose other materials, such as plastic or metal.

2.3 Installation of sealing materials: Install the selected sealing materials to the sealing area. Make sure the sealing material fits tightly and fills all voids and gaps. Depending on the actual needs, special tools such as clamps or wrenches can be used to help install the sealing material.

2.4 Apply pressure: After the sealing material is installed, apply pressure. This can be achieved in a variety of ways, such as using liquid or gas pressure pumps, or utilizing existing pipeline systems for pressure transfer. The pressure applied should be adjusted and controlled according to the actual situation and demand.

2.5 Testing and verification: After applying pressure, it is necessary to test and verify the sealing effect. This can be done using pressure sensors, leak detectors, or other detection equipment. Ensure that there are no leaks or leaks in the sealed area and verify that the sealing effect is as expected.

3. Applications with pressure plugging

Pressure plugging technology has been widely used in many industrial fields. Here are some common application scenarios:

3.1 Pipeline plugging: In the process of pipeline installation, maintenance or replacement, the pipeline needs to be blocked to prevent media leakage or external substances from entering. Pressure plugging technology can apply pressure to a specific location of the pipeline to achieve temporary sealing of the pipeline.

3.2 Tank sealing: In the petrochemical and other industries, it is often necessary to seal the storage tank to prevent leakage or the intrusion of external substances. Pressure plugging technology can ensure the sealing performance of the storage tank, thereby improving the protection of the working environment 3.3 Water treatment process: In the water treatment process, pipes, valves or other equipment need to be blocked to achieve water control and regulation. Pressure plugging technology enables temporary plugging in water treatment systems for easy repair, replacement or cleaning.

4. Advantages of pressure sealing

Pressure plugging technology has the following advantages 4.1 Fast and convenient: Pressure plugging technology can achieve temporary plugging in a short period of time, reducing downtime and production losses.

4.2 High flexibility: pressure sealing technology is suitable for all kinds of pipelines, containers and equipment, and can be flexibly adjusted and applied according to actual needs.

4.3 Stable and reliable: The sealing technology with pressure can ensure the sealing performance of the blocked area and improve work and environmental protection.

44 Economy and energy saving: pressure sealing technology can reduce the waste of energy and materials and improve the efficiency of resource utilization.

In SUMMARY:

Sealing with pressure is a kind of construction technology widely used in various industrial fields. It achieves temporary closure of liquid or gas in the blocked area by applying pressure to prevent leakage or the entry of external substances. The steps of pressure sealing technology include preparation, selection and installation of sealing materials, application of pressure, and inspection and verification. The technology has been widely used in the fields of pipeline sealing, tank sealing and water treatment technology, and has the advantages of fast and convenient, high flexibility, reliability and energy saving.
